Peace and pout: Pixie and Hunter, who have a combined Instagram following of over 120,000 people, shared a pram for the day and were both dressed in blue

Adding: '@huntercurtis doesn't totally agree.'

And Pixie's little face could be seen poking out from under her brother who appears to be squashing her.

The businesswoman and PR maven has dressed casually for the Saturday outing, sporting a pair of light blue denim jeans, which she has paired with a black and white striped sweater.

Her trademark blonde locks were curled to perfection as per usual and she was wearing minimal makeup.

'Walk away!' Last Saturday, Roxy took a rare swipe at her critics via a video of her son Hunter yelling at some birds in a Sydney park, with an accompanying caption for her detractors

Last Saturday, Roxy posted a video of Hunter confronting some birds in a Sydney park with an accompanying caption for her detractors.

'Walk away, birds, walk away!' the toddler yells at the off-camera fowl, before adding 'you suck, birds' as he himself walks away in apparent disgust.

Roxy added the not-so-subtle caption: 'So applicable right now! One for those & their opinions! I agree Hunty!'

Earlier, the mother-of-two uploaded a snap of the pair in the park, with the small boy looking cute in a blue beanie, puffy jacket, and a T-shirt with the words 'boys will be boys' emblazoned on the front.

On Sunday, the blonde businesswoman took Hunter and Pixie on a breakfast outing with her mother Doreen and pal Matt Flynn.

The trio posed together in one of Roxy’s signature lift selfies, where she showed off another expensive designer bag - a personalised Goyard tote - with a casual outfit.

Her children beamed in the mirror, both rugged up against the morning chill in heavy jackets.

Rugged up: In a following photo on Pixie’s Insatgram, maintained by Roxy, Hunter was seen clutching his comfort blanket wearing turned-up blue jeans and grey trainers below his jacket

In another photo on Pixie’s Instagram, maintained by Roxy, Hunter was seen clutching his comfort blanket wearing turned-up blue jeans and grey trainers below his jacket.

His sister sported similar jeans but with holes ripped in both knees and bright purple shoes, in addition to one of her famous red hair bows.

Roxy's barely veiled swipe at her critics marks a rare instance of her responding to negative publicity at all.

The last time was when she couldn’t help hitting back at an A Current Affair report into her spending the weekend immediately following husband Oliver Curtis' imprisonment at a five-star resort.

She took to social media minutes before the Channel 9 show aired to share a photograph of herself at work to prove she was not in hiding.

'Really A Current Affair 'Resort Roxy' .... On tonight's show? Looks like my bum and feet are firmly placed at my desk in my office,' she wrote alongside the photograph.

She was wearing the same clothes as earlier in the day when she was spotted with her children in what was her first public appearance since Oliver was jailed.

A Current Affair alleged the photo was taken at the Wolgan resort.

Difficult year: The PR guru has been spending a lot more time with her mother and children since Oliver, who she described as Pixie and Hunter's 'primary caregiver' because of her long hours, went to jail

Support: Roxy said having her mother's support as she tries to overcome her struggles has been a blessing

The PR guru has been spending a lot more time with her mother and children since Oliver, who she described as Pixie and Hunter’s 'primary caregiver' because of her long hours, went to jail.

And in another blow for the family, Roxy underwent various tests earlier this month after discovering a lump in her breast.

She told Daily Mail Australia that having her mother's support as she tries to overcome her struggles has been a blessing.

'Having my mum by my side who has suffered breast cancer and a mastectomy and come through fighting fit also makes things easier,' she said.

'Fear isn't an option, I have my Pixie and Hunter to look after so a clear mind and a proper plan of attack to get over this is the only thing that I think about.'
